Article 6: Why did modern human populations disperse from Africa ca. 60,000 years ago? A new model
Based on new research it has been found that origins of modern humans occurred approximately 150,000 to 200,000 years ago. After that there was a dispersal of these primates into Asia and Europe. The question that this paper sought to answer was why it took 100,000 years for this dispersal to happen from Africa. It was suggested that there was an increase in technological, economic, social and cognitive behavior that occurred and then the ability to expand to different regions of the world came. These radical changes were triggered by neurological mutations that allowed for greater cognitive capacities. The environment of Africa allowed for the …show more content…
This paper analyzes the remains of different skeletons from diverse regions in Asia. The Pleistocene was an epoch of evolution and dispersal of our ancestral populations. Fossils from this period are not as abundant in Asia but a handful are thoroughly dated and described in this paper. The primary criteria the authors had in deciding which fossil to use was that the fossils had to be well-dated and morphologically informative. The information suggested the dispersal was from Africa and later Asia. The authors noted the importance of keeping a clear chronological framework and conducting a complete morphological observation of the …show more content…
Even though many fossil specimens have been found in Asia and throughout other regions of the world, none of them are as deep-rooted as the ones found in Africa. There is much speculation about the reliability of fossils that are found in such ancient times, however we are able to see that Africa brings forth the majority of the fossils and the ones that are well preserved and dated. Therefore, in order for us to rule out the Out-of-Africa theory seems very improbable, there is too much noteworthy evidence pointing our ancestors to this
